how to reverse the motor??

i have your 230v/60hz fan motor, and need to reverse the direction ... the paper sticker how to do that is however faded away ...

there are 4 wires coming out .. blue, brown, black, yellow/green.
we have yellow/green to ground, and a small capacitor across two wires, and single phase 230vac.

the motor namplate has 3 numbers on it:
104-371
CC408-481
RH31M-4EK.2C.1R

Is it possible to reverse the directoin?

Dear Sir,

the mentioned fan is not designed to reverse the direction.
This has some reasons:
1. The impeller is only made for one direction.
2. The motor is only made for one direction.

Because of this the wiring is done internal and can't be changed.

Kind Regards
